12.3-2. Drying of Nitrogen and Scale-Up of Column. Using molecular sieves, water
vapor was removed from nitrogen gas in a packed bed {(33) at 233°C. The
column height was 0. 268 m, with the bulk density of the solid bed being equal.
to 712.8 kg/tn3. The initial water concentration in the solid was 0 01 kg
waterlkg solid and the mass velocity of the nitrogen gas was 4052 kgfmz- The initial water concentration in the gas was eo=926><10'5’ kg waterikg

(:1) Determine the break-point time, the fraction of total capacity used up to
the break point, the length of the unused bed, and the saturation loading capacity of the solid
03) For a proposed column length H;- = O. 40 tn, calculate the brealo-point time and fraction of total capacity used
